1. Lasers based on fractional photothermolysis were developed in order to minimize downtime and side effects associated with conventional non-fractional treatments, while maintaining similar clinical results. Fractional resurfacing creates areas of microscopically ablated and thermally affected columns, which are spatially separated by non-injured tissue. Fractional lasers can ablate deeper into the reticular dermis to induce neocollagenesis and a wound-healing effect1, providing clinical improvement for the treatment of photoaging, as well as scars. Scars can depress and widen over time, likely due to weakened collagen fibers in the underlying dermis.
2. Ablative CO2 fractional laser treatment for acne scarring in Asian skin has been reported to be safe and effective, resulting in normal re-epithelialization.
3. Ablative fractional laser therapy has also been shown to provide rapid wound healing with improvement in scar pliability, texture, durability, and range of motion.
4. Moreover, according to a recent consensus report, fractional ablative laser resurfacing, represents a promising and vastly underused tool in the multidisciplinary treatment of traumatic scars.
5. This report describes safe and effective CO2 fractional laser skin resurfacing and facial scar reduction in dark Fitzpatrick Skin Types IV-VI.
